Based off glamor's StyleSheet, thanks Sunil ❤️
high performance StyleSheet for css-in-js systems
- uses multiple style tags behind the scenes for millions of rules
- uses `insertRule` for appending in production for *much* faster performance
// usage
import { StyleSheet } from '@emotion/sheet'
let styleSheet = new StyleSheet({ key: '', container: document.head })
styleSheet.insert('#box { border: 1px solid red; }')
- appends a css rule into the stylesheet
styleSheet.flush()
- empties the stylesheet of all its contents
